DEFINITION OF TERMS

• DNA (Deoxyribonucleic Acid) (noun)– It is responsible for storing and transferring genetic information to make other cells.

• RNA (Ribonucleic Acid) (noun)- It transfers genetic code from the nucleus to the ribosomes to make proteins 

• Glucose(noun)- food of the cell

• ATP(noun)- energy produced by the glucose. 

• SYNTHESIS (verb)- process of creating or producing. 

• PROTEIN(noun)- are organic compound that provides structure to the cell and produces new molecules by reading genetic information in DNA. 

• CYTOLOGY (noun)- study of cells.

BRIEF HISTORY OF CELL

PREPARE YOUR PEN AND PAPER FOR NOTE TAKING

TINY COMPARTMENTS

•  In 1665, ROBERT HOOKE first discovered cell using a tiny piece of CORK under the microscope which he described as “TINY COMPARTMENTS” then later he called those compartments as CELL. 

"ANIMALCULES"

•   In 1674, ANTON VAN LEEUWENHOEK using a bacteria from a raindrop (Algae Spirogyra) discovered a live cell which he called ANIMALCULE.

• Algae Spirogyra is mostly found in what we call in tagalog as "lumot".

DISCOVERY OF NUCLEUS

•  1833, ROBERT BROWN discovered the nucleus in cells using an Orchid. 

• NUCLEUS is the center of the cell.

FIRST CELL THEORY

• 1838, MATHIAS SCHLEIDEN AND THOMAS SCHWANN who were studying plant and animal cells collaborated and proposed the CELL THEORY which states that the cell is the basic unit of structure of living things. 

• 
  

MODERN CELL THEORY

• 1858, RUDOLF VIRCHOW modified few tenets and discoveries of Schleiden and Schwann which is known today as the MODERN CELL THEORY

MEMORIZE THIS

• THE MODERN CELL THEORY STATES THAT:

Multiple Choice

Which organism is used by Anton Van Leeuwenhoek to study live cell?

• Algae Spirogyra

• Algae Spirillus

• Algae Specie

Multiple Choice

What did Robert Brown discover using an orchid?

• Nucleotides

• Nucleus

• Nucleons

Multiple Choice

Which of the following scientists provided the modern cell theory?

• Robert Hooke

• Rudolf Virchow

• Robert Brown

Multiple Choice

Which organism is used by Robert Hooke to study cell?

• orchid

• tiny piece of cork

• algae spirogyra

Multiple Choice

Who stated the first cell theory?

• Thomas Schwan and Mathias Schleiden

• Rudolf Virchow and Thomas Schwan

• Mathias Schleiden and Robert Hook

How many cells do we have in our body?

•  Organisms vary on the number of cell that makes them up. They can be: 

• MULTICELLULAR- composed of many cells. 

• UNICELLULAR- Single-celled.

Multiple Choice

In what category does human belong?

• MULTICELLULAR

• UNICELLULAR

TYPE OF CELLS ACCORDING TO THE PRESENCE OF NUCLEI (plural. Nucleus)

• Prokaryote- cells without nucleus and several organelles. 

• Eukaryote- cells with nucleus and membrane-bound organelles. 

Multiple Choice

Which type of cell do we have in our body?

• PROKARYOTIC CELL

• EUKARYOTIC CELL

STRUCTURE OF CELL

• REMEMBER: An ORGANELLE is a tiny cellular structure that performs specific functions within a cell.

• CLICK THE PLAY BUTTON TO WATCH THE VIDEO ON THE RIGHT SIDE OF THIS SLIDE.

• JOT DOWN ALL IMPORTANT DETAILS ESPECIALLY PARTS AND THEIR FUNCTIONS.

WRITE DOWN THE DIFFERENCES

AFTER THIS SLIDE, ANALYZE AND JOT DOWN THE PARTS, FUNCTIONS AND DIFFERENCES OF PLANT AND ANIMAL CELL

SUMMARY OF STRUCTURES AND FUNCTIONS OF CELL PARTS

• Animal cells and plant cells share the common components of a nucleus, cytoplasm, mitochondria and a cell membrane.

• Plant cells have three extra components, a  large vacuole, chloroplast and a cell wall

COMPARISON OF PLANT AND ANIMAL CELL

• Plants have CELL WALL for further protection. It gives the plant its rigid form

• The LARGE VACUOLE serves as storage of cell nutrients and disposal system.

• Plant cells have CHLOROPLASTS because they need it to capture sunlight and manufacture their own food.
